To all whom t may concern.-

Be it known that I, FREDERICK WILLIAM- No. 3,477, dated November 25, 1896; in New Zealand, No. 9,090, dated December 3, 1896; in Vest Australia, No. 1,409, dated December 3, 1896; in Great Britain, No. 29,926, dated December 29, 1896; in Canada, No. 54,964, dated February 11, 1897; in Belgium, No. 125,551, dated January 4,1897; in France, No. 262,779, dated January 4, 1897, and in Austria, No. 855/48, dated February 3, 1898,) of which the following is a specification.

This invention relates to improvements in ball-bearings and devices for adjusting and lubricating the same, which, though particularly devised for the purpose of being utilized on the axles or spindles of cycle-wheels, on the driving-spindle of cycle-gears, and on the spindles of cycle-pedals, are of great utility when applied to those purposesA where" spindles have to run in bearings and where journals have to revolve around spindles.

The invention consists in features of construction and novel combinations of parts in a ball-bearing, as hereinafter described and claimed.

In order that this invention may be clearly understood, reference will now be made to the drawings herewith, in which- Figure 1 is a central sectional elevation of one end of a wheel-hub and spindle in the fork of a bicycle, showing these improvements applied thereto. Fig. 2 is a similar view of a modified construction of the adjusting and lubricating devices according to this invention. Fig. 3

is a central sectional elevation of the driving or pedal spindle and bracket of a cycle having adjusting and lubricating ball-bearings constructed according to this invention.

A is the casting of the hub or boss of the bicycle-wheel, in which is fitted by sweating or otherwise the ball race or Way B.

F is theaxle or spindle, having at the one end (not shown) a sweated cone and a screwed cone or a solid cone adapted to take against the balls C in a similar race or way to that marked B. The adjusting-cone D carries,

fitted within a groove in its body, an elastic or semiflexible washerE, made, preferably, of leather, or, say, of elastic or semiliexible metal, and it has a cover-piece D', the outermost face of which carries serrations G, adapted to t in like serrations H, stamped or otherwise made in the end of the fork H' of a cycle. The ball race or way B has a groove or enlargement B', hereinafter called the lubricant-keep, and a contracted mouth B2 only sufficiently large to allow for the passage therethrough of the Washer E when contracted or folded. It is easily understood that the other end (not shown) of the hub or boss and of the spindle similar to these pointed out `has a cone, such as D, either solid or adjustable, an elastic washer E in such cone, and a lubricant-keep, such as B', in the ball-race,

and that it also has a contracted mouth B2, a cap or cover D', and, if necessary, serrations G and H. N ow it will be seen that the contracted mouth B2 and the washer E, whose normal position is, as shown, just bearing on the inside of the overhang of the contracted mouth B2, will effectually prevent the egress or escape of the lubricant and will also prevent the entrance of any dust or dirt. To adjust this bearing, it is only necessary to unscrew the nut F', slightly prize the fork or solid support H' outwardly until the serrations G and H are clear, and then turn, by means of a turn-screw or Spanner, the cap or cover D' of the cone D to the extent required `to adjust the bearing to the requisite degree,

which may be done the more minutely, as the serrations G and H are made smaller. Then, allowing the fork H to spring inwardly, the nut F is tightened and locks the bearings in their new adjustment.

Referring to Fig. 2, it is to be understood that this shows one end only of a hub or boss of a wheel, whose other end (not shown) is exactly similar. ing screwed thereon it may be driven on a taper, in which case the holes A would be convenient for driving it off for replacement when worn out. Said cone D2 might, however, be sweated on or it might be made solid with the casting of the hub A. In the cone is a groove for holding the elastic or semiflexible washer E. The ball race or way B4 screws onto the end of the spindle F and has contracted mouth B2, which passes over the washer E and then allows said washer to bear up against its internal overhang above the lubricant-keep B. The outer face of this ball-race has serrations G, and the rigid support or fork l-l has corresponding sei-rations l-I, the spindle having a tightening-nut F. As may be seen, the washer E in this case also prevents the exit of the lubricant and at the same time forms a dust and dirt proof barrier. The adjustment is achieved by loosening nut F, separating the serrations G and H, revolving the race or way B4 as required, and securing the serrations G and H tightly together by means of the nut F.

Referring to Fig. 3, the revolving spindle K has a cone part K, against which bear the balls C, kept and adjusted to their position by means of the race or way B5, screwed into the bracket or rigid support L. The cone K has grooves, in which is fixed the elastic or semiiiexible washer E, which runs in a lubricant-keep B, formed by the end of the race or Way B5, and a cover or cap M. The race or way B5 has sockets B3 therein for the purpose of taking the end of a Spanner or turn-screw, and the cover or cap M has corresponding through-holes M3, and it also has a contracted mouth M2. It is to be seen that the washer E by bearing up against the internal overhang of the mouth M2 excludes the dust and dirt from entering the bearing and prevents Instead of the cone D2 be` the exit of oil or lubricant from the keep B2. 5o

In adjustment the pintles or pins of a turnscrew or Spanner are placed in holes M3 and the jam of the cover or cap M on the race or way B5 slackened until holes M3 are in juxtaposition with sockets B3,when the pins of the turn-screw or spanner may be pushed through said holes M3 into the sockets B3, and the cover M and the race or way B5 both move backward or forward in their screw-thread in the bracket L, as is desired for adjustment. Then the lock of the Cotter-screw N being fastened, as well understood, the pins of the turn-screw or spanner are withdrawn from sockets B3 into holes M3 and the cover M screwed up on the race or way B5 as a jam-nut.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, what is claimed is l. In a ball-bearing, the combination of a ball race or way provided internally with a circumferential oil-keep having a contracted mouth, a spindle having thereon a cone provided with an inclined circumferential groove, an elastic and semiflexible washer secured obliquely in said groove,the said washer being adapted to be passed through the said contracted mouth and then assume its normal position to close the contracted mouth,thereby preventing the egress of oil and entrance ot dust, and the balls located between the said ball-race and cone,substantially as described.

2. In a ball-bearing, the combination of a spindle, a ball race or way provided with a circumferential oil-keep having a contracted mouth, an adjusting-cone having an inclined circumferential groove, an elastic and semi- .iexible washer secured in said cone-groove to guard the contracted mouth of the oil-keep, a set of balls between the said race and cone, and means for locking the parts together, substantially as described.

Dated this 13th day of November, 1896.
